I'll tell ya, those commodore 64 tape players are hard to come by. My brother still has the one he and I used back with C64 was in it's prime, but they are hard to find if you're out looking for one to buy or otherwise acquire.
Just for showing that in the photo is amazing to me.
"Sony Walkman and Commodore 64" is a nice fit the 80's challenge. Great use of some "antique" items to truly capture the era.
The image itself is very direct and to the point. I really don't think any voter would have confusion or question what you were taking an shot of. I do really like the placement of the subject, excellent use of the odd numbers. One thing I have noticed is a lot of the higher scoring images really use vibrant colors or images that tend to capture your eye. Your shot seems a little dull, with the coloring; maybe try to increase the contrast to see if it makes any of the object pop for the voter. I might even try to avoid the shadows since it feels like you were going for a very clean shot. Nice capture of the arena. Hopefully after the challenge you were able to pack these back up. Good work, can't wait to see what the future holds for your work.
