I think that you do not know what you are doing. The whole composition appears as most of the work is not done by you, the post is unclear in many aspects, you took mockups/screenshots from another person without any explanation.
To be considered for potential reward, submissions must include credits to all third-party images/assets used in the contribution.
You claim that the inner part is the icon for Steem. Later you say that the meaning is S for Steeditor.
In the last section, you even claim that png and psd are vector files. In my opinion you should know that it is far from the truth.
Since this was not chosen, we will see whether we can consider this work worthy of the reward.
your exploration is very reasonable. in terms of the criteria your logo gives an easy to understand opinion, but if you say I do not understand, that's wrong. because in terms of the PO logo Already say simple and strong. maybe in terms of logo explanation I have to learn to be easily understood by others. thank you
