I'd agree with kit an McPhisto - you really need to be able to draw.
Most designers I know and work with will even tell you they can't draw too well, including me...
But at the same time, we can all draw well enough to get a good grade in A Level art - which for most people is excellently.
I'll tell people I'm not a great drawer or painter - but when I say it I mean in comparison to genius like kit and mcphisto - not in comparison to the normal man off the street!
In summary - if you REALLY can't draw - you'll not be able to do this kind of stuff either!
I can't draw a matchstick man, let alone reach the heady heights that McPhisto and Kitster have achieved. Was never an artistic type unfortunately, but I so admire the work they can achieve on a machine.
McPhisto's Liverbirds are completely stunning, regardless of what pose he sets them in.
Kitster's player profiles are genius as well. Love the Torres and Skrtel characters he's produced. There's scope to work on the rest of the squad if he fancies it.
I wish I could produce something so fantastic via a computer, but I can't.
