Nie, but I think its a little dense. you might want to give some areas a little less detail, or tone down the contrast as onek suggested, just so your eyes have some breathing room.

The bricks look a little too uniform too, you might want to break up the grid a little.

Good start though!

beautiful tiles!! good work 

They look fantastic!  Keep up the great work.

thats some cozy looking grass there ^^  *wanna lay down!

altogether... tiles look a bit noisy/ chaotic,  maybe u could benefit from a bit more contrast. maybe add  shadows to the mushrooms to make them pop out more

transition from grass to dirt is quite angular and repeative
