Pretty good. Most people make a few, think they suck, then quit. Looks like you could do really well with this. Since you wanted a few pointers, or just helpful suggestions I guess, I can offer up a few:
- First things first. You want a clear background. The black is very distracting and not very pretty. I think there are a few ways to do this on the internet (websites and whatnot), but I just do it in paint.NET. The images you can download already come with clear backgrounds for spriting.
- Secondly, this is related to the first, if you don't already then I recommend pokemonelite2000.com as a spriting resource. It's definitely helped me out. If you right click, save as, and open the files that way, it should also solve the black backgrounds.
- Always, always, always save as a .png file. JPEGS are horribly blocky and rendered when saved. Saving as a .png fixes this.
- Clean up your sprites. Now, I'm definitely calling the kettle black here, because a few of my sprites are pretty messy if you zoom in enough and look closely. (You can partly faded blocks of color I didn't get out when I was experimenting with color.) Cleaning them up can go a long way towards making them more attractive.
- And finally, have fun. If you aren't having fun with a fusion, don't do it. Chances are, it will come out poorly because you didn't like it or expected it to.
Hope any of that helps.
