First: awesome character 
Second: just keep drawing!
Buy some printer paper, a ream of blank paper and just keep a few sheets with you at school
Never hesitate to use references to draw from. If you're eyeballing the reference you used, you've done a great job getting the point across.
If you go to DeviantART . com and look around, you'll probably find some instructive tutorials and images - check out their entire "stock art" area for good figure references and items.
There are a LOT of pretty good books out there available for drawing. The original "how to draw manga" books (the first two volumes, I should say) are *incredibly* good for learning what types of tools you can use, how to hold pen and pencil, basics of perspective and proportion, etc. Lighting, shading, folds, details those are things which you should work on after getting basics down.
I'm sure that there are a good number of folks here who can also point out links to help out!
Keep it up!
Please read my FEAR/Portal/HalfLife Fan Fiction!

I took your advice and got a how to draw manga book and I've been practicing and I'm slowing improving.
Once I get better enough that it's noticeable then I'll post more pictures.
Thank you? 
Practice makes perfect, as they say.
Keep working at it! Play around with half-sketches and other things, too, to focus on areas you feel you're having problem with (after all, you view of your work as an artist is pretty valuable).
Can't think of more motivators. Hmm. Must be low on coffee.
Hey Crescent, rockin' robot chicken.
Here is my suggestion: rough out the basic shapes of the entire body before adding in the robot-y details. If you start to work from the general & basic, and leave the specific stuff for last, it will help your whole picture look like the parts fit together. I think of it as making a paper doll to stick stuff on top of later. Sorry if that's a really ridiculous analogy. 
That is a ridiculous analogy in fact that's the best ridiculous analogy I have ever heard in my life and I thank you for that. 
And your advice on doing the robotic details last is also good. I'll try it.
I love all of you who have helped me out!
i love the costume on that alt and plan to rip it off later :P

Here's my second sketch that I just completed Sketch 2: Electric Boogaloo
And if you are going to rip my character then make sure to give me credit in your bio 
Can definately see some ideas coming to shape there.
Though, I can give you a few hints that I used during my (short lived) art career that really helped me out a bit, in capturing a certain 'feel' in a piece.
Practice, a LOT. But there are things you want to keep in mind when you DO practice that really make a difference towards actually learning something: You don't have to draw a full piece to really practice. Heck, you can do what I did for hours on end, and draw 'framework' (sort of what you did [assumption] on that piece, from what I can tell. Those are very familiar thin lines underneath the thicker bits. ) in various poses. What you have right now is a tendency towards a very 'static' pose. While not bad, it lacks energy... and getting energy into your art can go a long way towards fitting the images in your head.
You also don't even have to draw a full 'framework' or detailed piece, either. You can spend time positioning legs to get something you're happy with.. hands.. feet.. That sort of thing. Shading is worth focusing on, too, because that can create a fair amount of depth.
But, for the most part, keep on practicing. You're making some progress there.
So what you're saying is that I can catch more flies with vinegar than honey?
As in it would also be helpful to work on parts and experiment with them to get better and more skilled rather then keep drawing the whole thing.
Awesome idea 
It's the concept of micro over macro.
You get good at the little pieces, then you work on putting them altogether.
After all, any big project is really just a LOT of tiny projects put together.
Hi everyone, I'm trying out my art skills and I was wondering if anyone had some tips.
Here's a sketch I did during school, which is why it's on lined paper.
