You know, everybody starts somewhere, I at first started using gimp and made like really scary text in order to make something like this back when i was a noob
Am i gonna say your work is bad? Well, yeah but you're new. Everybody starts somewhere. I really hope you actually keep up designing and keep working on improving, remember to always take CnC to improve and never take it as a pinch of salt.
If you wanna get into more designing, I'd say you should focus on two programs, Cinema4D (3d texts etc) and Photoshop. These are your main tools and it should be something you should focus on learning if you wanna continue designing in the future. There's alot of guides out there that are super good.
Keep up the work mate, I'm glad to see someone trying to get into designing, and if you have any questions about anything in general about designs and whatnot, don't hesitate to leave a pm! :)
