Actually, the grass is just watercolor. I think I was using a small brush for it, but it's been so long since I've done this I honestly forget. ^^; As for the shading underneath them, I could slap myself. I can't believe I forgot that. Thanks for pointing that out.
Thanks again for the great comment. Kudos for you. :D
There's a lot of things I really like in this pic: the way the grass is colored (watercolor pencil?), the shading on the dragons' bodies, the expressions on their faces, the blue dragon's ears and fur and the red one's horns and frills... The Wind Waker-esque clouds are a nice touch, too, and really add to the fantasy feel of the comp. The one crit I have is that maybe the dragons could have some shadow beneath them so it looks like they're standing in the grass and not so much placed over it, but that's just a little thing; it's a really great pic, and so cute too! ^^
