You had to look when you read that "nudity" - part didn´t you ? 
Well, without any particular reason, here is some stuff I work with at the moment. I don´t have a "sketchbook" really, I draw on any piece of blank paper that happen to lay in reach of me...
Here comes the "nudity", not that horribble actually:

A request that has been a wip for a very long time...An anthro-character named Aheira, that yellow rope she is entangled in is supposed to be a Quetzal-coatl or feathered snake since this character resides in ancient Mexico...
This one (below) was originally intended for a weekly challenge here on the forum on the topic "Family pet" though it never came anywhere close to finished.

Well, it isn´t finished now either,...but I sort of like it so I will finish it, - probably... I am not sure if it will be in monochrome or colour yet,..this is one of the new ones, made with a Wacom-tablet !
And last; a typical raimo-sketch as they look before any computer-work, complete with holes and smeared paper:

I played a lot of Final Fantasy XII this summer and it is obvious whitch character I enjoyed the most...Her shoulder is wrong and that damn arrow looks crocked despite the use of a straight-ruler. Her ears should be longer but the great amateur raimo managed to missplace the character so parts of it got outside the paper as usual...Doubt that this one will be finished.
This is the character Fran from the game, sort of a "bunny-girl" you don´t mess with...
This game also gave me a new favourite artist: Yoshitaka Amano !
