Looks great, my only gripe would be the top of the c4d(?) acting as some sort of tail, at the top it looks pretty straight.
Love the colour blobs on the stock of the girl.


Incidentally I think the longest I've ever spent on a single piece of artwork was around 6-8 hours (a couple of times xD), and that was a vector (which always take me a while). Personally I don't think you should factor in the time taken to find the stocks - but thats just me.
Have you ever thought of creating the stocks yourself? Like using a studio or something?
