Hello, I’m gpz346, I create logos and thumbnails. I mainly use photopea or adobe photoshop. Feed back on my Icon and Thumbnails is very appreciated and if you would like to hire me you can message me on discord or on the Dev Forum.
You should not focus too much on outlines, mainly in black ones, try adding some more effects and also drop shadows, drop shadows do make a difference on it, also i would recomend you searching on YT “Gfx Comet” they have a lot of sick tutorials that u can learn awesome effects!
