I don't know much about 3D modelling, but the stuff you've made so far looks pretty cool!
That flower almost looks like some kind of jewel because of the colours and patterns hehe
Well when I did those teacups, it was literally my first week of modeling, so you can learn pretty fast!
I find certain parts kinda frustrating, as I actually made textures for the petal and it is not as intuitive as you think it would be to paint something. Well I guess if I just literally hand painted it it wouldn't be so bad, but trying to get the faces to work and saving the textures and what nots. That I have no idea if it's put into something else do I need to join everything and make it one object and one texture???
That probably didn't make any sense, but yeah! I made up a design and I like how it turned out. It almost looks like it could be a hard candy to me haha.
