Hey there, Callmedeedee, nice work on your poses, especially on your imagination and Spiderman poses, too.
If I could suggest an improvement, then it would be to caricature those poses more, in 2 days of 96 minutes(96 m/2 d=48 minutes) of 30 second poses, all from reference and/or from imagination. Would you please do those practices? The reason why???? Because, you really don't need to do your finished Spiderman poses in a time as short as 30 seconds, what you're supposed to go for, is the movement of those types of poses.
My hat's off to you, and I hope you've found this completely and definitely pleasurable, informative, and encouraging.
