New Tile set I'm working on need feedback

so I’m working on this tilemap
Grass.tilesWIPww
and I’m wondering if I should copy the tileset and make variations with flowers or should I add flowers that you can add on top of the blocks -thanks in advance for advice!

(10 years later) KingSlayer: you should do the flowers separate

I don’t know anything about tiles sorry

It’s good, I really like the style but quite frankly. The green grass is far to bright and neon green which is harsh on the eyes. Grass is supposed to be a background element so it’ll be hard to make elements above stand out. That said, I think you did a good job.

Also, when exporting your work to showcase on forums or social media, use the resize option to scale up by at least 500% so we can see details as browsers has filters on images. Zooming in makes images blurry.

right, thanks a lot is there a way to make a selected area and then change a color of my choice then change it to a different color?
