and welcome to the forum!
First off, i'd like to say nice job on your first and second sig!
I would try and Google "Photoshop brushes".
Or go to DeviantArt, and type in "Photoshop Brushes".
Start experimenting with those. They should really help you out.
Also, Dev.Art is an awesome place for tutorials. I would definitely go there or to YouTube if you want video tuts.
A great place for resources is PlanetRenders. Definitely check them out also! They have great renders + tuts. Also a nice place for stocks & fonts, and Photoshop PSD's.
I hope you stay here to improve.
