Welcome RedArmyMajor! Well you have come to the right place to learn. This is a fairly friendly community as well, so feel free to ask for feedback and advice. If you are a complete Newb then I'd recommend starting by spending a couple of hours browsing the tutorials section and collecting any walk-throughs that look interesting to you. If you already own Photoshop, wonderful, you own one of the best tools of the trade. If not, download GIMP 2.8 and begin practicing some of the GIMP tutorials. You can always add additional tools as needed, but GIMP is a good place to start.
