Buying a laptop is a complicated decision as there are lots of factors which are considerations in the compromise (eg, size, cost, performance -CPU/Graphics/Battery Life, looks, features - card reader/webcam/finger print sensor/availble ports/storage, reliability, vendor support, sound- speaker quality,/loudness, trackpad quality, etc.).
Lots of experience here.
Top two important factors are keyboard and display. (And sometimes - depends - trackpad quality.)
For you, your gonna want a good display. It's gonna probably be IPS of some kind plus have high contrast ratio and Adobe color compliance.
If your gonna do complex/specialty graphics you may want a good amount of ram (eg, 16GB min) and some kind of a decent graphics card.
The rest is what compromise you are able to stomach.
Good luck
