I think your quality is amazing. You have beutiful work. Always love to see what you bring to life.

I think all themes are good but the pictures that tell a story are always nice. And sweet romance ones too.

I am very happy with the art I got from you! I love it very much. I look at it regularly.

I'm so glad someone commented on it, because it's really important to me. Thank you!

I agree: the quality of your art is high; you are a strong, creative artist!
Honestly, I think every artist is best at what they enjoy. It would probably not make much sense to suggest to an artist who really loves, and is good at, drawing flowers to suddenly draw a complex building. Artists' passion will result in high quality work.
Likewise, you have passion for certain topics/scenes/ideas, and I think it is great that you pursue those - regardless of what anyone thinks.
Since you asked for an opinion, though, I will share that I personally prefer art that is light-hearted, sweet, romantic, humorous, positive, telling a story - and SFW.
But that is just me.

Thank you so much!
