i love this image, it looks very well done and it is not the exact same as the show and it is close but it is not close enough that it reaches into the 'uncanny valley.' it is rather innocent in design between the two of them but it seems it could go further but also not. They are simply enjoying themselves and acting like little kids which is good so vision gets a 4 star rating for all of this. It is very original with that they are at a beach which they never went to in the show, and no one else has thought of to put the two together in. this gets a five star rating from me. The technique is great and has a lot of detail on the entire picture and many colors are used making it very effective in technique. this gets 4.5 stars from me. Finally, the impact is not what i would be used to in Spike Belle images with them not having any romantic events going on so it is different but good different. it would be a great jumping off point for a relationship as them being good friends and having fun together. heck, they don't even have to get together, maybe it just enhances their friendship. any ways, it gets 4 stars from me. great job on this picture and i hope to see more images like this from you soon
We already know that Spike has a crush on older sister Rarity, plus he now has an example in his own family of good friends becoming family through marriage (Princess Cadance marrying Shining Armor to become Twilight's sister-in-law). If Rarity is "too old", he might "settle" for Sweetie Belle instead, who in terms of relative age is only slightly less mature than he is, and become an in-law to Rarity that way.
All that, of course, would be a very long way off yet.
