Your pictures are amazing, you have a new follower of your work! My sister is photographer too!
I can help you with your slogan, but before a mockup, i need to know what do you want that the people feel with it, why the photography is your passion, your begings. Contact me, talk is free!. discuss a little and i will give a Mockup.
Agree?
By the way, if you contact me or not, i want to tell you that i loved your think in the dream store website, you have reason on it, if more people could think and see the life with your perspective (and lense), surely the world can be better.
