Common frog

[Nowhow]

Hi all,

It is my first time here (as a contribitur that is). Although I have ZBrush for a while now, I only made doodles untill now. For a project I needed a common European frog (Rana temporaria) and I didn't want to draw it over and over again in different angles. So this was a good time to really start learning ZBrush!
It is still a work in progress: I still need to ad good webs between the toes and I am still adding detail to the skin. Also the joint between the leg and the foot needs to be a little bit smoother.

I made a small turntable for you to look at: common frog (http://www.youtube.com/watch?v=RD-t8ITJTWg) Sorry for the language, I am Dutch! ;)
Here is an image, I already made some shadows in Photoshop, but it still needs some work.

I have an additional question and I figure it is available in the documentation, but I haven't found it yet: I want to render the image on a high resolution (300 dpi app. letter size) without seeing the ragged edges. Can someone tell me where to find the solution for that?
