hi Nivardy!!
this is absolutely a good first step - i think getting started with a comic youre really passionate about is a brilliant way to start learning and improving and becoming the Comics God you wanna be. remember, as you push on with this comic and discover your style, that you can reboot sometime when youre more confident with your art. whats important now is pushing on to create Something, preferably complete, and to put passion into it.
two quick tips for 'crud!'
1: you might wanna try using a layer of fill shading or some heavy blacks - they could really lift some of your panels and add interest. shadings great for keeping a reader's focus and guiding their attention. it doesnt have to be anything severe - just a feint blue overlay layer blocking out shadows could do a world of good. this resource might help
2: study colour theory itll change your life. (sorry i only have on resource, i didnt seem to bookmark a lot
but there are a lot of great resources on colour theory on dA and tumblr and the one i DID link you is a doozy imo)
good luck, man! youve got a long and exciting journey ahead of you.
