Awww, adorable! I just love Loki's expression, it's hilarious, he clearly doesn't care much for some time with his brother And I like how Loki is holding a book and Thor a sword I like Loki's closed-off, lordly silhouette and the warrior-like energy in Thor's pose. Also, I really like your colouring style, the dots make such a lovely texture effect!
Thank you so much and sorry for the late reply >__<!! I think the most interesting thing between this brother are their compared personality and appearance~~ so i just paint it! And i'm still trying different colouring ways Glad you like it!!
