I liked part A
Nice work! The only problem I see is that you used the same synth melody line throughout the ENTIRE piece. I'd only use it in your B section (it seems to work best with those rhythms). The good news is, if you take that part out of your A section, there is another synth line already there that you can use for your melody. That means, aside from cutting it in A and C, the only thing left to do would be to find a new melody for the C section. You can do it! Ask me if you need help.
