Christel, I love them all!!! They are some great paintings!
The red flower is just wow - popping out on the black bg, wonderful flame-like petals... great!
I do like your adjustments with the bg for tulips - very nice and pleasing work.
The animals are fun! I especially like the last one, because I can see lots of details on his face
C & C welcome, I intend to get better with OPs
Get inspired with various artists' beautiful OP paintings
