Hi EverGrey, and welcome to ThePhotoForum.
I have been to look at your indoor flower photos more than only now, it is only now I can say hallo to you, though.
The first one is very crisp, good focus. Personally, though, I am no big fan of the light here. But as I am saying: that is a very personal opinion. On-camera flash does not go well with flower photography is what I think.
But you are obviously off to a very good start and as soon as spring comes round and the flowers begin to bloom in the gardens and parks, you can go there . Can't wait for that time to come back!
