Welcome, Sahetah! Your jewelry is very pretty. I love the look of the open rings in your necklace, and those earrings look like something I'd wear.
Please don't be intimidated! Nobody here bites very hard.

Even those artists who are very successful and experienced had a beginning.
I hear you about the photography! Getting good product photos has been one of my biggest struggles, and I feel like I'm finally beginning to get decent at it (though I still have a lot to learn)!
Kudos to you for taking care of your grandfather. That takes a lot of strength, and I admire that sacrifice.
