You do need some practice, I will tell you this. If you look in my scraps, you'll see Choco Pony and Fairy Unipony, which were early tablet works. It did take me at least a month to get used to the transition between mouse to tablet.
I adore her face and mane. It really feels like a suspended movement, like it's all going to keep going in just a second. ^_^ Excellent composition...Her fins are really cool, too. For me, her tail feels too thin for her body, but then, I suppose a real seahorse looks rather the same way, so. Lovely work!!
Thank you. Yeah this is why I like drawing seaponies, since they're underwater it's..somehow easier for me to give a sense of movement. I dunno. Yeah, her tail's a little thin there for a seapony, I thought something looked off.
