Firstly, Instagram is one thing and this forum is another. Not trying to be rude, but you can't expect from everyone to reply to your thread and expect commissions to happen just like that. For example, some people may like your art but they may not have money right now. In all honesty, I do like your art but I would pay more money for something really good (digital art) instead of wasting money on something less-professional.
Everyone has its taste.
