I'd like to place my opinion here. Please don't take this as a bad thing but instead, please look at it as a chance to improve.

With the 5 photos on your portfolio, I thought it was kind of easy to replicate so better watch out for that. Plus, I didn't like the 'Tie Dye Diffraction' one because the white BTC logo didn't harmonize with the bg.
You have potential. A large room for improvement.
