Lovely! oh, and I know what you mean. Iman in sooooooooo difficult to draw. It's like any small mistake shows, because she has such a specific face. (and I'm not saying David doesn't, but I've had more practice drawing him. lol )
No, it's not bad, *raises hand guiltily* I'm the same way. And not purposely I assure you! I feel your pain though, it's so difficult to get that dark shade of skin color and it really forces you to put a lot of work and thinking into it.
I haven't seen the original pic, however, any pic. of these two always shows their love. It's so sweet! And I agree entirely!
