work on your lighting mine isnt real good either but the 1st is better at that. Also try using diff Grayscaling maps and try get the hang of some fx. There are plenty of free tuts to follow on the internet just Google some tutorial sites up.
1st is made only from tutorial, 2nd I improvised a bit. The most tutorials have all i know, I know basics of Photoshop. Maybe you got some advanced turorial?
