I like you first image, a lot of people have bad first images, I had really bad ones, there are a lot of programs you can use, I personally like Apophysis, try that, if you want to know how to get it just ask me, all of my images were made using that program, also Terragen is also easy to use, it makes landscape images but you have to be kinda good with that one or all of your images will look a little boring. Remember keep me updated every time you upload!

With regards to my image Doodle3 Please check my gallery and find the image called the process this shows i did in fact draw this image. The video you saw must have been a similar image but not my one. The idea for this image came from a 3d model. Which i then drew and used as a shading exersize
