Hmm... I'm kinda baffled how we're supposed to help with such a widespread help request.
What exactly do you want us to help with?:
2D Drawing with Pen and Paper
2D Drawing with a Program like Photoshop using a Tablet
3D Modelling with a Program like 3DS Max
Kitbashing a Scalemodel using various Materials and lots of glue
You really might want to be a little more specific what you want to do.
Except for the Kitbashing I'm doing all of the above but none of them are particularly easy:
Traditional 2D Drawing with Pen and Paper requires quite some understanding of how Perspective works to achieve a result that is also pleasing to the eyes of others.
Perspective mistakes are, at least in my opinion, the major reason something looks bad cause it can't be covered with "artistic freedom". It's either Yes or No.
Anatomy is another thing when drawing Humanoids or Animals. People thend to intuitively know when something is anatomically wrong even it they don't quite know what it is.
A
Pen or Pencil that feels good is enough and you're ready to go - No excuse not to do something.
Example using a Ballpoint Pen
2D Drawing with a Program like Photoshop using a Tablet builds on the same experience like Traditional 2D Drawings with a Pen and Paper with the added benefit of beeing able to make quick and clean changes to your actual ( or past ) Projects within seconds.
Personally I'm using a
Wacom Cintiq 21UX which is a Pen-Enabled Monitor giving me a 1:1 experience of working ON the medium rather than NEXT to it like with Tablets.
I'm looking forward to the MS Surface PRO in hopes for beeing able to use it as a Pen-Enabled Tablet on the go.
Example using the Wacom Cintiq 21UX
3D Modelling with Program like 3DS Max is pretty much the next stage. It easens the pain with perspective as the Program is doing it for you but it's probably the least intuitive artform when starting to learn it.
You could theoretically use the 3D Modelling to make your own references for 2D Drawings!
If you find great love doing 3D Modelling I'd recommend to use a 6D Mouse to work in 3D Space - I'm using a
3DConnexion SpacePilot PRO which makes navigating in 3D Space like flying.
Example using 3DS Max and the SpacePilot PRO
Like I said, you might want to be a little more specific what you want to do and where you need help.
