@RedIzak Welcome to meow!  

You should add some hashtags to this post for better discoverability, like
#/introduction #/Furry #/FurryArt #/MastoArt #digitalart
(posts here can be edited)

@RedIzak
Glad to help  

You should also add descriptions (alt text) to images, just telling in a few words what what's in an image. It can make posts easier to search and is also helpful for people with impaired vision. Mastodon's culture encourages using them and people are more likely to boost art that has descriptions

@RedIzak There's no formatting rules. You can just write sentences, e.g. for the first image something like:

An anthro wolf thief in leather armor jumping over a wall, holding a bag of coins

(In the post editor click on "No description added" on the images)

@RedIzak It works!

If you're also looking for mobile apps for Mastodon, besides the official one I recommend Tusky (for Android) and Ice Cubes (for iOS)

@RedIzak
I'm happy to help!

When writing a post, you can also set its language. Looks like it's set to PL for you by default, you should change the posting language in the settings to English in the settings if you're primarily going to write in English.
