Say I wanted to create some artwork to this standard:

Would adobe photoshop 9 enable me to do drawings to this quality? I cant afford adobe photoshop and am only doing this for a hobby, so dont see the point in spending alot of money on the software.

So is adobe photoshop 9 still good? can I create some good work like this with it?
