Hi @andrejcibik, thanks for your feedback. below are my response to your comments:

• logo was simplified, with flat look
• removed unnecessary details to make it visible even in smaller resolution
• I also provided sample of logo when used in single color
• still in .psd format, but the shapes are in vector shapes which is "scalable" & printable in big format

I hope my effort could help on the approval of my contribution.
Thanks again for looking into my post.
