Feed the Pupper - Rika pinup sketch

Usually i'll come up with a few doodles to pick from for the monthly pinup, but sometimes I just have  an idea sold in my head already. Rika being all dog-like with an all-fours or tail-wagging pose was what came to mind.

I attached a chest-down version, but I think for the pinup I'll go with the  all-fours, and I can think of a number of good alts to this piece. Feel free to toss out any ideas for those, too! I like hearing  what's come up. Enjoy the sketches; I'll probably stream working on this tomorrow (Monday), and do the request stream for March #1 either this Friday or Sunday.
