general critque/advice

hi , i just put some stuff together that ive done over the past month or so. i feel like im happy with my form and flow for the most part - but is there anything i should work to improve ? general concepts to push towards , or any small consistent errors to point out? any feedback at all is appreciated!
thank you !
