Heya!
Hey, that sounds like a lovely idea! I’d say go for it if you’d really like to start it up! It can be a bit scary and cause some doubt to start up any blog, but you never know what could happen until you try it!
There always is that bit of chance that someone out there may not like what you do. But that doesn’t mean no one will like it! I mainly started a Tumblr a looong while back just to have an extra place to share my art (as I was already on a few art websites beforehand), so I didn’t really have that fear creating this blog.
It does take time for anyone to gain followers, watchers, or anything on any website, do keep that in mind! But if you’re determined and keep at it, no doubt some folks will notice you, and share your blog around!
I have faith in you! You’ll get the confidence soon, I’m sure! <3
