1. What was the exact reason Adobe gave you for rejection? For example, technical reasons, model release needed, intellectual property?
2. Did you include a model release for picture 1?
3. Did you include a property release for picture 2? Did you make the light yourself, or buy it, or find it?
The first photo is underexposed to the point of details are lost in the shadows and there is a blue color fringe on the edge.
The second photo is also underexposed and too much is out of focus.
When posting here you need to state what the moderators say the photo is rejected for. To find that information on your contributor page click on Uploaded files, then Not accepted. On the new page, click on the image in question and read what is said on the right of the page.
I would also add that in the first image, the label "SPORT" on his toque would also need to be removed as another IP violation. I also think from a composition point of view, the fuschia coloured curtain(?) in the right of the frame is quite distracting. When viewing the image at 100% magnification on a large screen, it is very noisy. Original on the left and "denoised" on the right. With your original RAW file, you should have even better results.
Your fist is noisy and has several (at least) 2 IP issues, as pointed to before. Blacks are missing as shown in the histogram.
I agree with @reedesign1912 that the pink curtain should be cropped out or photoshopped.
The picture is not sharp. At f1.8 you have a very small margin to get the eyes in focus.
As for the second image, you probably have an IP issue and the picture is simply out of focus.
