Half bath drain & wet vent

[DIYluke]

Good morning.
I was hoping some of the professionals could look at my half bath drawing and let me know if it looks acceptable or what I've done wrong.
I'm planning on wet venting the WC through the 2" lavatory drain because I can't get a vent to the toilet without at least a portion of it being horizontal below the flood rim.

Thank you all in advance.

Does anyone have an opportunity to look at this?
Did I even post this correctly that people can see it?
