These drawings are great, I am personally a really big fan of simple pencil/pen and paper drawings! Keep up the awesome work, hopefully you can get a scanner so that you don't lose as much detail when uploading them from your phone. Also, photoshop really is not that necessary. I use GIMP with Gimp Paint Studio, and I feel that it is a very complete program with all the tools necessary to get the job done. It even uses brushes from photoshop, which is really one of the most important things when doing digital drawings. Best of all, GIMP is a free program, although I wouldn't mind getting photoshop...
