Yah, I know I draw them a lot, but I like pulling character out of their Pokemon designs and trying to make it look good in human form, not entirely human, but not 'a pokemon standing up'. They're fun for me, anyway. I don't go for the extremely easy ones like Gardevoir, but I like at least a little challenge. Just not a MissingNo or extremely-obscure type of challenge.
Ahh I see what you mean, I might try and pick a more challenging one because it was actually Gardevoir that kinda sparked the interest when I saw a pic of it with boobs x____X; XD (not an interest in that aspect but you know what I mean)
Oh! Well as a first, I think that'd be fine if you did it, really. I was just saying, for myself, if I tried to do a Gardevoir, I'd get bored quick, or I wouldn't be able to keep up with it because I already knew what it was going to look like since it's already very human like.
MissingNo has been done quite a bit actually, and some of their works are okay, but it's such a hard one to pull features from that a lot of people just sort of go with the general shape, and then make a human with similarly colored clothes, and posed in that shape. So it doesn't give enough features to really pull from, which is why it can be challenging.
I'd say try a Gardevoir first, and then if something else catches your eye, give it a try afterward. I should probably sketch out a few at least while I'm art-blocked, maybe that'd help me out a little..
