I need some feedback for my blog

Hi,

I am working on my site and trying to improve it day by day but one problem i am facing that whenever i see a nice website i compare with mine and it triggers me to change my layout. so i need some feedback where i can justify myself what people say about it.

Site - http://www.digitaldevnet.com

I am trying to target or achieve sending traffic to amazon so i can earn something
but i am confuse about niche, I am not sure whats my niche but still am targeting people who want to develop digital banner campaigns as i am good in it doing banners and animation
programming.

audience i am looking for startups or small business owners where i can help them and i can earn something in return so i can quit fulltime job and be my own boss! (my dream)!

Well, you might be thing do i am expertise to be that.
Something about me, from high school am doing good in design and earn some certificates
later move into small production house where i worked as nonlinear video editor, start doing animations and build website. Meantime i work on my 3D skill as something 3d logo required in videos. Luckly, I got job as 3D designer and move into another creative dimension. I worked few years as designer and develop my interest in online game development. I develop some stuff and got job as developer. Now I develop stuff for digital agency as programmer but my interest in things not stopped and learning from digital agency I am into digital marketing. I got certification in digital marketing, however, I am trying my best to move into digital project manager position which sound very difficult but achievable.

I am trying to build my stuff online where I can start something of my own but u need to earn something to be somewhere in a position. Well, I am looking for feedback for my site.
