I wouldn't call yourself "by no means a good composer yet"! These are great tracks and this submission is very imaginative with how you inserted yourself into it as a means of fitting the theme. Starting with a cinematic track for a trailer is an awesome choice. I especially love the sound effect-like bits that play in the title track, little flourishes like that definitely add a lot to it. The battle theme really reminds me a lot of Mega Man, I could see it fitting in perfectly in one of the NES games.
Overall, great submission! It feels really unique and nice.
