I would really appreciate any advice on my prints. I am using a Sintron MK8 extruder with a Prusia i3 acrylic frame. Ramps 1.4 with merlin (default installed from Sintron). I had to do a lot of tweaking and some custom work to get this thing to a printable state.
Here is the first print.

Please tell me how these look and what can I do to improve the quality.
The print engine is Repetier Host with the Curaengine as the slicer.
Thanks and this is my first time building a printer or printing. I value your input.
I will add please don't throw g code at me. I am a visual learner. thanks.
