Are you looking for just subscribers? I mean personally I prefer people who generally want to read my comics because they enjoy what I make. I mean subs don't mean much if those subs aren't actually reading what you make, trust me I know. I mean if you really just want a sub I don't mind just subbing to you, but don't feel obligated to return the favor unless you generally like what I make. Personally as someone who only started in April and already have 24 subs I think you're doing just fine mate. Keep up the hard work you'll get more subs with a little more time, schools starting and there's plenty of people who have downtime now to waste on the internet.
