Sacisaurus

So, basically I am making a Sacisaurus rn and it will be the first ever creature with sexual dimorphism that I made, so I'd like to ask you guys on what are the inaccuracies of this Sacisaurus

Btw art is by FreddyFan95 on DeviantArt to me it looks almost like the actual animal surprisingly

So, yeah I drew Sacisaurus in the art style of I'm A Dinosaur, sorry if it looks weird I used MS Paint to make this one because I can't use FREAKING IBIS BECAUSE MY PHONES ARE ACTING UP ON ME. But I was thinking about creating The Land Before Time characters in the I'm A Dinosaur style
