No. You can't take a donation for professional services/time you donate, only for actual out of pocket expenses incurred in making the donation, e.g., mileage to and from; cost of renting equipment for the job, etc. Buying equipment or items which you will own and use, no.

Love 3 & 4, I agree with the others, the tree is better left out. Good eye.
Nice. Are the colors (flower, butterfly) soft in real life or are they processed?
