seriously dude it looks great. Considering you seem to be just starting off in digital art, this is a -great- start. Even my comics don't look that good and I've been doing them for years now (all in digital art with Photoshop and SAI). I mean, everyone's stuff has room for improvement and it's never perfect, but this is already looking pretty sweet. You've got a cell-shaded look going on, which gives it a very crisp and visually satisfying look. It's bold and pleasing to the eye.
However, maybe cell-shading isn't the way you wanna go? I'm not familiar with the Fire Alpaca program but if it has a blur or smudge tool, which it should if it thinks it can call itself a drawing program, then try to familiarize yourself with those tools because then you can blend your colors and get a much softer feel. But for something like this, cel-shading works 
So don't call yourself "amateurish". Everyone improves every day with their work and no one is perfect, right off the bat (if ever). Just keep practicing and you'll see improvement in no time (:
